Do I need Indoor Setup (also known as white glove service) or can I do it myself?

- The chairs are easy to assemble.  It only takes about 20 minutes.  The only reason assembly is required is because most chairs ship with the arms detached to make it narrower, lighter and easier to move into your home.

- The assembly is basically just screwing the arms to the chair.  It includes easy to follow instructions and does not require special tools or skills.

- If you want them to setup the chair inside your home, you can select the option for “Indoor Setup & Assembly”.  We don't recommend it for most people it because it's an easy way to save yourself the money.  But we're happy to add it to your order if you'd like.



Canadian customers

- Yes, we ship many massage chairs to Canada.  Total turnaround time is typically about 2 and a half weeks.  We make it easy by handling all of the importing paperwork.  We also pay for the customs brokerage and filing fees. 

- GST (usually 4.9%) and duties if levied, would be billed to the customer.  Duties have never been levied on massage chairs we’ve shipped to Canada.

A qualified technician would be sent to your home to provide service if you ever need it. You never have to ship the chair for service.

Reviews & Ratings

It's amazing just like what I expectedReview by jonnyzhu
I did a lot of researches before I place this order. It's amazing just like what I expected. I use it every day. (Posted on 10/16/2017)
By far, the BEST VALUE and HIGHEST QUALITY Massage chair on the market !!!! And, we did MANY hours of research !Review by Rita Johnson
We are SO IMPRESSED with this chair !!! We researched all the chairs from Osaki and the 4000LS sounded like the newest, most innovative model of massage chair made by Osaki. We also, researched all the other chairs on the market and concluded that this was BY FAR the best "bang for our buck". We WERE NOT DISAPPOINTED ! Excellent quality, super therapeutic massage (LOVE the foot rollers !!!!) and the heat is a BIG PLUS. We joke that we'll have to stay married for ever since if we ever divorced, it would cost us a fortune in legal fees fighting over the "custody" of this chair :) (Posted on 1/18/2017)
